Abstract

In the rapidly evolving landscape of Intelligent Transportation Systems (ITS), Vehicular Ad-hoc Networks (VANETs) play a critical role in enhancing road safety and traffic flow. However, VANETs face significant security and privacy challenges due to their high mobility, dynamic topology, and reliance on open wireless communication. This study addresses the critical question of enhancing the security and privacy of VANET communications amidst the challenges of high mobility, dynamic topology, and the threat of various cyber-attacks. This paper presents a comprehensive solution to enhance the security of VANETs by introducing a novel Physically Unclonable Function (PUF)-based authentication scheme. Our approach leverages the intrinsic security features of PUFs, integrating them with lightweight cryptography to fortify the network against physical acquisition attacks and ensure secure communication over potentially insecure channels. The proposed scheme is meticulously designed to address the unique security and privacy requirements of VANETs, offering a scalable and resilient framework for authenticating and managing the network's entities. Through an extensive evaluation using a realistic experimental setup, our solution demonstrates its efficacy in providing a secure, reliable, and efficient authentication mechanism for VANETs. The scheme balances computational efficiency with advanced security features, making it well-suited for the resource-constrained environment of vehicular networks.
